It Only Took 66 Million Years, But A T-Rex Is Finally Making Its US Debut

This bony being is an ambassador from an Earth without humans. But it is also an individual with a personal history: a tale - and a tail - that has touched ranchers, researchers and dinosaur lovers for years.

The bones of a Tyrannosaurus rex were brought to the Museum of the Rockies, where a replica now stands.

A long time ago, in a part of this state that is now arid desert but was then humid swampland, an egg hatched. It was the beginning of an epoch-spanning life story that continues still, beginning a new chapter this week in the US capital.

The egg is long gone. The skin and muscle of the animal that climbed out of it - 38 feet long and six tons once it grew - are history (or prehistory). But when it died on the banks of a creek after 18 good years at the top of the food chain, its bones settled into the enveloping mud. The current teased away the flesh, pushed its skull a few feet downstream, shifted a shoulder blade.

But more sediment filtered down, locking the skeleton in a geologic hug that would go unbroken - through 66 million winters, the collision of continents, the rise of mammals - until just before 9 am on Labor Day in 1988, when Kathy Wankel caught a glimpse of that shoulder blade.

"It was right over there, just a bit of it sticking from the earth that caught my eye," Wankel said 31 years later on her first return to the site that changed her family story and will now become part of her country's story, too. The "Wankel T rex", one of the largest and most complete skeletons of the meat-eating dinosaur ever found, will debut June 8 as the star attraction of the newly refurbished, $110 million fossil hall at the Smithsonian National Museum of Natural History.

For all its ferocious reptile rep, scientists still debate whether the living Tyrannosaurus rex was a dominant predator or just a toothy scavenger, feasting hyena-like on the carrion of the late Cretaceous. But today, their fossilized remains reign unchallenged over paleo-pop culture, the iconic king of all the dinos portrayed in movies, played with in kids' bedrooms and displayed in museums. The Smithsonian - which had a replica T rex towering over visitors in its old dinosaur exhibit - has been desperate for a real one for decades. They are thrilled to get such a prime specimen as the one Kathy Wankel spotted that September morning.

"It's the centerpiece," said Kirk Johnson, director of the museum and a noted paleontologist (who thinks T rex was a predator). "It's the anchor of the whole exhibit, and it's going to bring a lot of joy and excitement."

Kathy and Tom Wankel work on their ranch in Montana. In 1988 they discovered a T-Rex skeleton on a small island in the Fort Peck Reservoir.

This bony being is an ambassador from an Earth without humans. But it is also an individual with a personal history: a tale - and a tail - that has touched ranchers, researchers and dinosaur lovers for years.

The history of the skeleton known to Montanans as the "Wankel T rex," to the Smithsonian as the "Nation's T rex" and to scientists as "MOR555," has three parts. The first we know little about - researchers can't even tell whether that hatchling was a girl or a boy. The second part was 24 billion days of stony silence. But the third ... that's where it got interesting.

The Discovery

Kathy Hove was born in Mississippi near the border with Louisiana, where, coincidently, the wide, warm and wet forests are a pretty good facsimile of what Eastern Montana looked like before the Rocky Mountains rose up to block all that moisture flowing from the west. But she grew up in Montana, where she married lanky Tom Wankel, her high school sweetie. They started a spread in the treeless badlands where ranchers scratch a living and paleontologists scrape for fossils.

They'd been at it a dozen years when they took the three kids camping up at Fort Peck Lake, a dammed-up section of the Missouri River close to the border with Saskatchewan.

"I like to fish; Kathy likes to rock hound," said Tom, 69, on a recent spring morning in the living room of the ranch house where they still live, surrounded by 250 heads of Black Angus and about 40 cats. It's 18 miles to the nearest paved road.

Geologists know the area as the Hell Creek Formation, a vast swath of land eroded just enough to uncover the layers of time and earth where dinosaurs once walked. Kathy knew to look for bones and stones alike.

It was drought time; Yellowstone National Park 400 miles to the south was on fire and the lake level was down dramatically, allowing her to scour widely along the shore. That's where she was when a small protrusion from the slope - like the corner of an envelope - stopped her roving eye. She bent closer.

"The light was just perfect," said Kathy, who was 35 that morning and is 66 now. "I could even see the webby pattern of the bone marrow."

She called Tom, who scrambled up the slope. They pondered a lot and poked a bit, but the hard-baked clay was too much for his pocket knife, and the kids had school, so the waiting bones would wait some more.

It was about a month before they could return. They came in the fall, found the spot and chipped a set of long bones from the rock. For the first time since its final breath, the T rex - or part of it - was on the move, bouncing down a ranch road in an orange cooler that does beer duty for the Wankels to this day.

Kathy washed the fossilized bones in the sink on the back porch, lay them on the basement ping-pong table amid her collected agates and quartz and wondered: Who do you call when you find a dinosaur?

The Museum of the Rockies started out as a Quonset hut packed with Old West memorabilia on the campus of Montana State University in Bozeman. But it was already gaining status as a hotbed of paleontology by the late 1980s, when a phone call from a rancher out in Hell Creek territory led to its biggest boost yet.

A replica of the "Nation's T rex" sits outside the Museum of the Rockies, where the family first brought the dinosaur's bones.

It was Thanksgiving break when the Wankels loaded the bones on a cardboard meat tray and drove them 350 miles west to Bozeman. In an autumn snow, they backed their station wagon up to the museum loading dock. Pat Leiggi, then the chief fossil preparator, walked out without much expectation.

"We get a lot of calls from people saying they'd 'found something,' " said Leiggi, remembering the moment at the same loading dock three decades later. "We end up looking at a lot of rocks."

He went out, peered in the back window for a long moment, then looked up at the Wankels. "You'd better come inside."

Jack Horner, the museum's founding curator of paleontology (and reportedly the model for the dinosaur expert in "Jurassic Park"), had never seen the lower arm bone of T rex before. None had ever been found. When Leiggi and the Wankels filed into his lab with their cardboard trays, that changed.

"It was obvious what it was," he recalled in an interview.

"They were all in there with their Marlboros just a-puffin'," Kathy said. "They'd puff and look down and puff and look down. And then Jack said, 'Could you show us where you found these?' "

The Dig

The T rex was buried in layers of earth and bureaucracy alike. It was nestled on the shore of a federal reservoir at the edge of a national wildlife refuge, and figuring out who controlled the land, getting permissions and Montana's short summer field season meant it was more than a year before Leiggi and his crew set up camp and started to jackhammer in earnest.

"Right over there is where we had the kitchen," Leiggi said, pointing to a spot at the base of a slope on a recent May morning. He had joined the Wankel family on their first trip back to the spot since that month of excavation.

It was a big dig. The Army Corps of Engineers bulldozed a road, and the science series "Nova" set up a time-lapse camera to track progress. Only about eight T rex skeletons had been uncovered at that time, Horner recalled. They knew they had a big one.

Leiggi and colleagues had partly uncovered the animal's spine in a test dig the season before, protecting the find under a "winter jacket" of plaster and hiding it under sage brush. Now, with brute force and fine finger-work in turn, they removed more than 60 tons of cap rock until the outlines of the beast revealed itself, still in its agonal pose, its neck thrown back in the rigor of death.

Once they had measured and photographed every bone in its prehistoric posture, they encased whole sections in plaster and lifted them, surrounding rock and all, with Army Corps bulldozers. The pelvic bloc alone weighed more than 7,000 pounds. They would expose them completely over the next several years at a specially constructed display lab at the museum.

"It was beautifully articulated," said Leiggi, who is now the museum's director of paleontology, looking down on the shallow dent still visible decades later. He kicked at a chip of Reagan-era plaster. "I should have done a better job cleaning up this site."

Wankel's T rex, estimated to contain almost 90 percent of the living animal's bones, quickly became a favorite with visitors and researchers alike.

The Wankel family and the paleontology team recently revisited the discovery site as they prepare for the T rex's debut at the Smithsonian this week.

"I've had a lot of T rexes in my life, but MOR555 was special," said Mary Schweitzer, a paleontologist at North Carolina State University. Her work on the specimen as a graduate assistant led to her groundbreaking - and controversial - claims of finding molecular-level residue of blood cells and soft tissue in dinosaur fossils.

The Wankels enjoyed that the "Wankel T rex" was so renowned. Replicas were made for museums in Scotland, Australia and California. Kathy went on "To Tell the Truth," where David Niven and football star Lynn Swann grilled her about fossil finding. When the Museum of the Rockies put up a massive bronze cast of the skeleton out front, they went for another round of congratulations.

And then, in 2014, word reached the ranch: Their T rex was heading to the nation's capital. The Smithsonian had arranged a 50-year loan with the Army Corps, the legal owners of the skeleton.

To The Capital

It was a bittersweet departure for many when they packed 16 crates of T rex into a customized FedEx truck and pointed it east. A lot of Montanans like Montana fossils to stay in Montana. Johnson, at the Smithsonian, hopes they will take solace that it is likely to become the most viewed T rex in history.

The 7 million people who visit the museum each year "are going to see it and know it's from Montana," he said.

It's taken a long time to make the shift. The Smithsonian spent five years completely renovating the fossil hall, revamping its collection and restoring the Beaux-Arts architecture. The T rex, in the meantime, was going to stand up for the first time.

In Bozeman, the fossils had been displayed in an array of pieces, showing visitors what Leiggi and Horner saw when they first uncovered the bones.

"A death pose gives the visitors a chance to see what it looks like in the ground," Horner said.

Kathy and Tom Wankel, who live on a ranch in Montana, discovered the dinosaur's remains in 1988.

The Smithsonian has opted for an action pose, sending the fossils to a firm in Ontario for mounting in a dramatic tableau of life and death on the subtropical basin that was Montana back, back, back in the day. Now, the fossilized T rex is frozen in the act of chomping the head of a fossilized triceratops. Whether it is the chomp of a predator or a scavenger is left for the visitor to imagine.

"People can think he killed it, but maybe he just found it," said Johnson, even as his staff was putting the final touches on the new exhibit. "It's best to be clear about where your knowledge ends and speculation begins."

The Wankels and their three all-grown-up kids are coming to see their find take its place as Washington's newest bigfoot VIP. They will get a private tour of the exhibit and take in a Nationals baseball game, and Tom will put on a black string tie for the opening gala crowded with people, some of whom have donated a lot of money to get their name on a plaque somewhere in the Smithsonian.

Kathy Wankel has her name on one by a different route. She came arm-in-arm with a dinosaur.
